I love these goggles - the fan actually works at keeping fog away, and they fit very well over my glasses.

I have a number of different lenses for different conditions - which is nice. I particularly like the Sensor mirror.

Only downside is that they are very big and look a little goofy, even with a helmet.

These goggles worked fairly well. I still had some fogging on the glasses I wear but not on the goggles themselves. The battery lasted a long time considering I used it on 2 days where the temp started at minus 9. The lens are good when overcast, but way too clear for any sun like conditions. However, when I used my prescription sun glasses it worked perfect. Allows me to switch back and forth easily on partly cloudy days.

The fan is wonderful just a slide of the switch wait a couple of seconds and the fog is gone! Glad I spent a little extra for this option, well worth it!

I've used these bad boys 3 times thus far and they perform well--at night, and in partly cloudy and cloudy conditions. I have not used them on a sunny day yet.

But, with my current helmet, they push down on my big nose and affect my breathing. If I can't get the right helmet combo, I'll need to return these puppies to BC.com.

I don't think I have excessively large glasses-- I have some older OTG goggles that fit my old and new glasses, but both pair hit the lens on these with enough pressure to make them uncomfortable (and would damage the lens.) I had to return them, which was not a problem.

...I can wear goggles while skiing.

I have to disagree with what eri2807363 mentioned in his review. I have a pretty large head and wide glasses. I also tend to overheat very quickly resulting in never having been able to wear goggles while skiing before. My previous OTG goggles were pretty worthless to me (and smaller than these). I've been night skiing four times so far with these goggles and they've worked almost 100% of the time. There was only one instance where I actually had to take them off when I made the mistake of trying to ski slightly uphill and they just wouldn't unfog.

I will say that the headstrap is definitely too small to fit over a helmet (which I currently don't own--though I have a larger than average head). Also, after the first time I used it, I mistakenly left the fan switch to "on" so the batteries obviously died when I next needed to use them. So that's certainly something to keep in mind.

Overall, these goggles have been great. After never having been able to wear goggles before, these were a lifesaver.

I bought these for my husband who tried them out last Sunday... he loved them. He was able to see well and with his glasses on all the time under the goggles they did not fog up... What a plus!!! he really likes them and will conitnue with these great goggles he highly recommends them
